    • Abstract


      It is shown that the fluorescence spectrum of Cs2UO2(NO3)4 consists mainly of sequences starting off from the resonance bandR followed by ‘C’ the bending frequency and each consisting of bands which can be assigned as (A, B, A + C), (2A, A + B, 2A + C), (3A, 2A + B, 3A + C), etc., where A is the symmetric vibration frequency,B the antisymmetric frequency and C the bending frequency of the linear UO2/++ ion in this lattice. In addition are observed several fundamental frequencies of the nitrate ion and the lattice either alone or coupled to the symmetric frequency A and its overtones. The relevant constants are:
